Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: 1) Narrow down target/match revision to u8 in nft_compat. 2) Bail out with unused flags in nft_compat. 3) Restrict layer 4 protocol to u16 in nft_compat. 4) Remove static in pipapo get command that slipped through when reducing set memory footprint. 5) Follow up incremental fix for the ipset performance regression, this includes the missing gc cancellation, from Jozsef Kadlecsik. 6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0 as no filtering, from Felix Huettner. 7) Reject direction for NFT_CT_ID. 8) Use timestamp to check for set element expiration while transaction is handled to prevent garbage collection from removing set elements that were just added by this transaction. Packet path and netlink dump/get path still use current time to check for expiration. 9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal. 10) map_index needs to be percpu and per-set, not just percpu. At this time its possible for a pipapo set to fill the all-zero part with ones and take the 'might have bits set' as 'start-from-zero' area. From Florian Westphal. This includes three patches: - Change scratchpad area to a structure that provides space for a per-set-and-cpu toggle and uses it of the percpu one. - Add a new free helper to prepare for the next patch. - Remove the scratch_aligned pointer and makes AVX2 implementation use the exact same memory addresses for read/store of the matching state. netfilter pull request 24-02-08 * tag 'nf-24-02-08' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_set_pipapo: remove scratch_aligned pointer netfilter: nft_set_pipapo: add helper to release pcpu scratch area netfilter: nft_set_pipapo: store index in scratch maps netfilter: nft_set_rbtree: skip end interval element from gc netfilter: nfnetlink_queue: un-break NF_REPEAT netfilter: nf_tables: use timestamp to check for set element timeout netfilter: nft_ct: reject direction for ct id netfilter: ctnetlink: fix filtering for zone 0 netfilter: ipset: Missing gc cancellations fixed netfilter: nft_set_pipapo: remove static in nft_pipapo_get() netfilter: nft_compat: restrict match/target protocol to u16 netfilter: nft_compat: reject unused compat flag netfilter: nft_compat: narrow down revision to unsigned 8-bits ==================== Link: https://lore.kernel.org/r/20240208112834.1433-1-pablo@netfilter.orgSigned-off-by:Paolo Abeni <pabeni@redhat.com>

use ->scratch for both avx2 and the generic implementation. After previous change the scratch->map member is always aligned properly for AVX2, so we can just use scratch->map in AVX2 too. The alignoff delta is stored in the scratchpad so we can reconstruct the correct address to free the area again.

Florian Westphal authored
Pipapo needs a scratchpad area to keep state during matching. This state can be large and thus cannot reside on stack. Each set preallocates percpu areas for this. On each match stage, one scratchpad half starts with all-zero and the other is inited to all-ones. At the end of each stage, the half that starts with all-ones is always zero. Before next field is tested, pointers to the two halves are swapped, i.e. resmap pointer turns into fill pointer and vice versa. After the last field has been processed, pipapo stashes the index toggle in a percpu variable, with assumption that next packet will start with the all-zero half and sets all bits in the other to 1. This isn't reliable. There can be multiple sets and we can't be sure that the upper and lower half of all set scratch map is always in sync (lookups can be conditional), so one set might have swapped, but other might not have been queried. Thus we need to keep the index per-set-and-cpu, just like the scratchpad. Note that this bug fix is incomplete, there is a related issue. avx2 and normal implementation might use slightly different areas of the map array space due to the avx2 alignment requirements, so m->scratch (generic/fallback implementation) and ->scratch_aligned (avx) may partially overlap. scratch and scratch_aligned are not distinct objects, the latter is just the aligned address of the former. After this change, write to scratch_align->map_index may write to scratch->map, so this issue becomes more prominent, we can set to 1 a bit in the supposedly-all-zero area of scratch->map[]. A followup patch will remove the scratch_aligned and makes generic and avx code use the same (aligned) area. Its done in a separate change to ease review.

Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.

Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af8 ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

Eric Dumazet says: ==================== net: more factorization in cleanup_net() paths This series is inspired by recent syzbot reports hinting to RTNL and workqueue abuses. rtnl_lock() is unfair to (single threaded) cleanup_net(), because many threads can cause contention on it. This series adds a new (struct pernet_operations) method, so that cleanup_net() can hold RTNL longer once it finally acquires it. It also factorizes unregister_netdevice_many(), to further reduce stalls in cleanup_net().

exit_batch_rtnl() is called while RTNL is held, and devices to be unregistered can be queued in the dev_kill_list. This saves one rtnl_lock()/rtnl_unlock() pair and one unregister_netdevice_many() call. Signed-off-by:

This saves one rtnl_lock()/rtnl_unlock() pair per netns and one unregister_netdevice_many() call. v4: (Paolo feedback : https://netdev-3.bots.linux.dev/vmksft-net/results/453141/17-udpgro-fwd-sh/stdout ) - Changed vxlan_destroy_tunnels() to use vxlan_dellink() instead of unregister_netdevice_queue to propely remove devices from vn->vxlan_list. - vxlan_destroy_tunnels() can simply iterate one list (vn->vxlan_list) to find all devices in the most efficient way. - Moved sanity checks in a separate vxlan_exit_net() method.

unregister_nexthop_notifier() assumes the caller does not hold rtnl. We need in the following patch to use it from a context already holding rtnl. Add __unregister_nexthop_notifier(). unregister_nexthop_notifier() becomes a wrapper. Signed-off-by:

This saves one rtnl_lock()/rtnl_unlock() pair, and one unregister_netdevice_many() call. Note: it should be possible to remove the synchronize_net() call from geneve_sock_release() in a future patch. v4: move WARN_ON_ONCE(!list_empty(&gn->sock_list)) into geneve_exit_net(), after devices have been unregistered.
